Build the legends of tomorrow (Rip Hunter, White Canary, Atom, Firestorm, Heatwave & Captain Cold, Hawkgirl & Hawkman).
Live action, no Marvel/DC.
Guy who works for a Time Travel Agency, steals their tech and goes rogue to rescue someone he cares for:
LT. AL CALAVICCI
After Sam Beckett disappears, Al discovers the Quantum Leap Project has been running a parallel project and developed a working time ship, hanging Sam out to dry as they no longer need the data he was providing.
Al steals the ship, and gathers a crew, determined to find Sam, somewhere in time.
Hot female well trained in kicking ass, dresses in white, can pilot the ship:
COL. WILMA DEERING
Used to providing support to hot head Buck Rogers, she doesnt mind going on a time adventure. She gets a break from saving his ass, and gets returned with no one the wiser.
Nice guy scientist, kinda goofy, who has developed size changing technology:
WAYNE SZALINSKI
He's not 100% on board with this, but he really cant say no. This Al guy needs help, and his family has said they'll wait for him and that he's doing a good thing.
Two guys in one body guy:
LT. TUCK PENDLETON & JACK PUTTER
Working with Wayne Szalinski, they've refined their miniaturization tech to allow them to switch places at will, or both be full sized simultaneously. When one's inside the other their physical stats double.
These two will run maintenance on the ship.
A couple of guys recruited for their criminal expertise and ability to kick ass:
ROY O'BANNON & CHON WANG
Their wanted posters show they had decent prices on their heads.
Al figures a couple of guys used to being on the wrong end of things, and breaking the law will come in handy, once they get over the strangeness of their new situation.
Battle couple who should be together, but arent, due to their complicated "history":
EMMA PEEL & JOHN STEED
Well versed in espionage, able to think on their feet and fight, all while dressed quite sharply. They take to time travelling with typical British stiff upper lips.
